I am an astrophysicist within the Laboratoire Franco-Chilien d'Astronomie (LFCA) (Unité Mixte Internationale of the CNRS) hosted by the Pontificia Universidad Católica de Chile's Instituto de Astrofíca.

I defended my PhD thesis, entitled "Optical Spectra of Thermonuclear Supernovae in the Local and Distant Universe", at the Ludwig-Maximilians Universität (Munich, Germany) in November 2005.

During my postdoc at the Harvard-Smithsonian Center for Astrophysics (CfA) I founded the CfA Supernova Archive, where you can freely download light curves and spectra of many supernovae.

You can view my CV here [pdf]
